In my fic 'Call Me Alpha' the way the omegaverse works it a bit different than how it usually does. At least in the fics/hcs I've read.
I'll break it down into each second gender to make it easier, starting with;
Omegas-- Have sweet scents or either fruit or flowers, with a hint of something else. usually two key scents can be detected; primary, either fruit or flower, and secondary, which is dependent on the interpretation of whoever is scenting them. Generally, it's just a variation of seet, like honey.
An omegas first heat is not sexual at all in nature. It is the most painful heat they will ever experience, and lasts between one to two hours. This heat is present during their presentation, and presentation happens between ages 11-13, with some exceptions.
The second heat is the more sexual, but relatively tame. If the omega has been sexual, or engaged in intercourse, than their partner, if they have one, will be able to help them through it. These heats happen between ages 16-18, and can be medically induced if it doesn't happen by age 19.
Omegas are not limited to the submissive and weak personality, but can be string and independent as well. Older generations believe that an omegas purpose is to serve their alpha, this is not true. Omegas can be independent, on their own, and carry on being single.
Omegas can also bond with each other, but cannot mate. Yes there is a difference, I will explain later. Omegas can only procreate with betas or alphas, but can adopt as long as there is two or more of age omegas in one household. Omegas are territorial over their nests, but get along well with every second gender.
Omegas are incredibly creative creatures; they are the artists, chefs, interior designers, and gardeners of the working force.
Betas-- I've seen a lot of people saying that betas are like the normal humans. This is not true in my fic. When a beta presents, they tend to get sick like a normal fever, and will either pass out or puke from pai I their head and neck. Their scents are mild and calming, like the smell of the ocean or fire, or rain.
Betas are natural caregivers, providers and peacemakers. They make up the largest portion of doctors, judges, teachers and politicians.
While they do have to most level headed and neutral approach to problems and conflicts, they are not immune to pheromones. They also release their own. These pheromones are used to suppress and subdue any pheromones getting in the way of thinking.
Betas don't have heats or ruts, but can help out where needed in those cases. Betas also nest, but not to the degree that omegas do. Betas can bond with both alphas and omegas, but can only be mated by the others. Again I will explain this. Beta and beta relationships are most common when it comes to second genders pairing off with each other.
Alphas-- alphas are the most aggressive and territorial, but are able to cull these instincts if taught properly. Alphas scents are sweet, but not as sweet as an omegas. Still distinct in their own way; the primary scent is sweet like spices or herbs, and the second is the same as an omega.
Alphas are the leaders, but not the asshole kind. At least less assholeish than certain fics I've read. They are the presidents and prime minister, managers, ceos. But they are also strong and stubborn, so they are also the heroes, and laborers of society. An alphas job is to protect and provide, and these instincts are harder to cull than others.
And alphas first run is similar to an omegas in the sense that it is not sexual. They usually get agitated, aggressive and sometimes possessive over friends if they feel threatened. This lasts one to two hours. The second rut is tame and less painful, but will be more intense if they had any sexual encounters before.
Alphas also nest, but in the sense that their whole room or sometimes house is their nest/den. An alphas den is their safe space, and they are the most territorial when it comes to things that belong to them.
They can bond with all other second gender, but can only mate with omegas or betas. Alpha and alpha relationships are less common, but are still seen. These relationships are when alphas don't find omegas or betas attractive.
Bonding-- a bite mark that symbolizes an active and ongoing relationship with one or more partners. These are temporary, lasting only a few weeks to a month, and need to be 'renewed' when they fade. These marks are always beside neck scent glands. These tell any and all other people that this person is off limits, but doesn't decrease the allure.
Mating-- can only be done between; omega and alpha; alpha and beta; and beta and omega. Omegas can't mate omegas, and alphas can't mate alphas. Betas dont mate, they get mated.
Mating is like staking a permanent claim on another. This can only be don't if both parties are consenting, but can only be don't by alphas or omegas. These marks are bite marks on the scent glands, and these decrease the scent and allure of both parties.
Additional info-- when a person first presents, they get their individual scent, before that, they smell like their family members and friends. Only presented people can smell other people scents, so an unpretentious child cannot smell rheir alpha parents scent.
A child's behavior is indicative of what their second gender will be, but this is not always the case.
Family members cannot be 'turned on' by pheromones released during heats or ruts.
Most families have a large nest where they all sleep in until the child is around 5-7 years old, then they are taught how to make their own nest.
Omegas, both genders, and betas, only female, can bear children. Alphas, bothe genders and betas, male, all have males aligned reproductive organs.
Classes in schools usually have a pack dynamic, but can also have smaller packs like friend goups; friend groups outside of classes are packs, and families are also packs.
Lonely people, if alone for long enough, will suffer from a deepset depression. These will become fatal if left to develop long enough.
Fated ones are people who's scents are similar in their secondary scent, so for example: alphas scent is cinnamon and maple, and omegas scent is roses and honey. These scents are unique to the individual though. There is also the feeling of want and desire which transcends mating and bonds.
If a mate or bonded dies, the mark will be nullified, but the pain is excruciating.
